Version 4.2.9

Intro

The following documentation describes the data dictionary for the Canvas Data warehouse. Following typical data warehouse conventions, the database records from canvas are transformed into a fact and dimension tables. Put succinctly, fact tables contain measurements and dimension tables contain the different dimensions that can be used to slice and aggregate the data (see Dimensional Modeling). Canvas Data mostly adheres to a Star schema convention, which means that most of the relations should only be one join away (see Star schema). These tables are either available as a set of flat files or hosted in a Amazon Redshift instance which is optimized for a range of analytical queries. For help with Canvas Data, please try posting on the JIVE forum. For more information on Canvas Data, please contact your CSM.

Notes

  • All timestamps in Canvas Data are UTC
